What is FlashCardPrinter?

FlashCardPrinter is a lean framework for printing flash cards.
Flash cards help you learn your vocabulary or similar things that can be
described in a few words. Flash cards are typically used in a
flash card box
according to the
Leitner System.
Each of the cards contains a question on the front side and the answer on the
back side. You check the knowledge of each cards several times with increasing
time between.

To give you a more practical idea of the whole thing here is my current
box with a set of cards in each of the stages:

The front group contains a set of freshly printed cards.

Once I knew the answer I put it into the second group. This
group is check every day. All cards I failed to remember go back in the
first group.

The third group is basically checked in intervals of 2 days. But I prefer
putting additional cards in it so I can check the subgroup every day.

The forth group follows the same principle at intervals of 4 days. Again,
there are 4 subgroups. Each of the according white cards contains the week day
when I have to check next.

Once a card reaches stage 5 I put it into a bigger box and check it a week
or two later. After that it is checked 2 or more weeks later and so on.

Very important: You should learn your vocabulary in both directions.
For that reason I have a second box for the opposite direction. For the sake
of simplicity I move the cards at stage 5 from the yellow box to a second box
in orange.

The amount of times to repeat the cards and the times between each stage
depends fully on you. Some people might prefer longer times especially in higher
stages, others may even stop at the fifth stage.

You should also use a really good card box as you will use it daily. Mine has
a lid which can be pushed below the container and closes firmly when not in
use. The boxes for higher stages can be simple cardboard boxes, maybe just old
shoe boxes.

There are also applications
which keep track of your knowledge. I wrote one
myself years ago. But in the meanwhile I really prefer the antiquated
approach.
